This series includes various fixes aiming to enable test_progs run
with userspace address sanitizer on BPF CI.
The first patch fixes the selftests/bpf/test_progs build with:
SAN_CFLAGS="-fsanitize=address -fno-omit-frame-pointer"
The subsequent patches fix bugs reported by the address sanitizer on
attempt to run the tests.
---
v1->v2:
- rebase on bpf (v1 was targeting bpf-next)
- add ASAN flag handling in selftests/bpf/Makefile (Eduard)
- don't override SIGSEGV handler in test_progs with ASAN (Eduard)
- add error messages in detect_bpftool_path (Mykyta)
- various nits (Eduard, Jiri, Mykyta, Alexis)
v1: https://lore.kernel.org/bpf/20260212011356.3266753-1-ihor.solodrai@linux.dev/
